The main object of this invention is to provide an umbrella frame which may bev en.- tirely collapsed so that the'same may be conveniently folded and stored in an ordinary pocket.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing. y

Referring briefly to the drawing, Figure 1 is a 'front elevational view of theframe in elongated position'in which it is ordinarily used.

Figure 2 is a sectional elevational view of the handle, showing the same in collapsed Figure 3 1s a fragmentary view of a section of the rib, showing the means of support-ing the outer or end rib member bythe arrangement provided.

Figure 4 is a view similar to Figure 3, showing the rib sections in folded positlon.

Referring in detail to the drawlng, the numeral indicates a solid stud circular in cross section and upon which a pair of rings 11 and 12 are adapted to be slipped, the ring 11 being secured rigid after being sllpped into place on the stud 10. The stud 10 is slidably mounted in a length of tubing 13 which is provided with a flanged upper end 14 engaged by a lug 15 formed at vthe lower end of the stud 10. An additional tubular section 16 is adapted to receive the section 13 and isV in turn adapted to telescope into a lower tubular section 17 which is flared outwardly at its lower end to provide a handle grip 18. A slot 19 is formed in the tubular section 16 and extends thru the greater portion of the length of said sleeve having an off-set slot 2O at its lower end, said slot communicating With the longitudinal slot 19. A pin 21 anchored to and projectingfrom the side of the tube 13 ismovable in the slot 19 and when entered into the slo't- 20, is adapted to fix member 13 within member 16. A similar longitudinalv slot 22 is formed with the lower tube 17 and at its lower end also has an olf-set slot 23 in either of which a pin 24 fixed to the lower end of the tube 16 is slidable. A relatively long coil spring 25 is mounted within the tubular sections between the bottom 26 of the lowest tubular section and t-he bottom of the stud 10, as illustrated in Figure 2. A plurality of ribs 27 are pivotally joined to the upper ring 11 and radiate outwardly therefrom. Each of these v lsupporting ring 32 passes. supporting ring is pivotaly Vr1b section 27 and extends ownwardly semirib' sections `terminate in a downwardly extending boss orV ear 28'in which a pin 29 is anchored.` To these pins, the support ribs`30 are pivoted, the opposite ends of said support ribs being pivotally anchored to the lower ring 12- which 'is centered on the stud 10. These support ribs are each provided with a slot 31 thru which a semi-circular One end of said attached to the circularly having its opposite end pivotally Y secured at theA corner of a boss 33 formed on the end ribs 34, said end ribs being pivotf' ally joined to the outer ends of the rib sections 27 by plates 35. l

In collapsing the umbrella frame, the two rings 11 and 12 are slipped from the stud 10 upon which they are normally mounted when the umbrella is in use. The supporting ribs 30 are then urged upwardly to align with the ring to come as close as possible to the ring 11. In doing this, the supporting ribs 30 fall into position parallel with the rings 27, which position is arrived at when the rib sections 27 suspended vertically downward from the ringmember 11. After this has been accomplished, the end rib members 34 are rotated upwardly so that these end ribs lie inta position indicated in Figure 4, in which they extend parallel to the rib sections 27. rIhe handle illustrated in Figure 2, being a separate member, may be telescoped by sliding section 16 into section 17, and section 13 into section 16, and the stud 10 into the tubular section 13. As member 16 is completely telescoped into the tubular section 17, both ends of the handle are twisted in opposite directions so that the pin 24 anchored to the tubular section 16 enters into the slot 23 and fixes member 16 within the lower tubular section 17. The tube 13, forming an intermediate part of the handle,is locked in telescoped position with the tube 16 in the same manner by rotating member 13 when the same has been completely collapsed into the tube 16 so that said pin 21 enters into the off-set yslot 20. In the manner described, it will be seen that an umbrella frame is presented which is completely collapsible into two sections, the shed frame which may be folded into a compact bundle half the length of a rib, and a handle which may be telescoped to one quarter of the length. The fabric ordinarily used to cover the rib sections is herein omitted for the sake of clarity, but it is to be noted that an expanse of material is to be used over the rib sections 27 and 34 as a protective covering.

I claim An umbrella frame comprising a pair of rings, a handle bar supporting said rings, ribs extendingradially vfrom said rings, said ribs comprising twomembers, a rib member attached to the ring and an endy rib member pivotally attached to the outer end of said rib supporting ribs i'or supporting the outer ends of the irst-named rib sections, thetwo members forming a `rib being placed end to end and pivotally connected@4 semi-circular ring pivotally connected to the mutually adjacent ends of the rib sections, the supporting ribs having slots therein serving as a passage for the semi-circular rings, the

end of said slot being adapted to form a stop for vthe ring` members When the latter are supporting thev end rib sections in used position said ring member serving as a brace for supporting` the end rib section in angular extended position.
